Gas engine lubricating oil composition and preparation method and application thereof

Abstract

The invention relates to a gas engine lubricating oil composition which is formed by mixing oil soluble polyalkylene glycol base oil, a clearing agent, a dispersing agent, zinc dialkyl dithiophosphate, an antioxidant, a pour point reducer and neutral base oil in a certain proportion. The invention further relates to a preparation method of the gas engine lubricating oil composition and application of the gas engine lubricating oil composition. According to the gas engine lubricating oil composition, the phenomenon that a large amount of sediment exists in existing gas engine lubricating oil is avoided, the defects that abrasion is intensified, working temperature of lubricating oil is increased and oxidative deterioration of lubricating oil is accelerated due to the fact that a large amount of sediment exists in existing gas engine lubricating oil are overcome, and the service life of lubricating oil is prolonged.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a lubricating oil composition for a gas engine. Background technique [0002] Due to the high combustion temperature of the gas engine and the lack of lubricity of the gas itself, the gas engine has strict requirements on the deposits. Excessive deposits will cause problems such as increased wear, increased energy consumption, and poor heat dissipation of the gas engine. In the actual application of the traditional I, II, III, and IV base oils blended in a certain form, the gas engine lubricating oil still has a lot of deposits, which leads to aggravated wear and an increase in the operating temperature of the lubricating oil. , leading to accelerated oxidation and deterioration of the lubricating oil, thereby shortening the service life of the lubricating oil. Therefore, finding a base oil component that does not generate deposits and has a certain inhibitory effect on the format...
